Hi all,
I know this is not a typical question for a user list but I least I can try to find help here;-) I have given a vehicle (it's a point) and the movementpath of the vehicle (it's a "directed" linestring) ! I computed the degree of the movement! For example moving from (0,0) to (0.5) the movement direction is/has 0 degree (0,0) to (5.0) the movement direction is/has 90 degree (0,0) to (0.-5) the movement direction is/has 180 degree (0,0) to (-5.0) the movement direction is/has 270 degree but for visualization each vehicle occupies a rectangle and I want to compute the position of the rectangle "!beneath!" the street! So I have given a point(vehicles point on the streetnetwork) the movementdegree and the distance(width of the rectangle/2)! And I need to compute the point! (situation is shown in attachment) My idea is for computing the point (x,y) is: x = sin(degree)* distance + x(value of point on street) y = cos(degree)*distance+y(value of point on street) What do you say? Is the formular correct? Cheers, Martin
